What type of engine oil is suitable for the new Geely Emgrand?
1 Answers
SAE10W-30 is the recommended engine oil specification for the new Geely Emgrand. When the ambient temperature is below 0°C, SAE5W-30 can be used instead. Naturally aspirated engines can use mineral or synthetic oil, while turbocharged engines require synthetic oil. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity - 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the vehicle. The second number represents the kinematic viscosity at 100°C - higher values indicate better ability to maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The oil change procedure for the new Geely Emgrand is as follows: Wait for the engine temperature to cool down, allowing the oil to drain back to the oil pan; Loosen the drain plug with a wrench and collect the old oil in a container until it stops flowing. Start the engine for about 30 seconds to allow oil in the main oil gallery to drain out; Remove the oil filter with a special wrench; apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add new oil through the valve cover filler port - typically about three-quarters of a standard oil container; Run the engine for 5 minutes and check for leaks around the drain plug and oil filter. Repair if necessary; After stopping the engine, check the oil level with the dipstick to ensure it's within the standard range.
